High Alumina Bricks are a kind of commonly used refractory materials for sale in RS Company, which is mainly made of Al2O3. High Alumina Brick has properties of high refractoriness, high strength, acid and washing erosion resistance, good thermal stability and so on.
high alumina insulation brick is often used because of its ability to withstand thousands of and other types of hightemperature facilities
Description for Magnesia Carbon Bricks. Magnesia Carbon Brick, a kind of unburned carbon composite refractory, are manufactured with magnesium oxide of alkaline oxide with highmeltingpoint (2800℃) and carbon material with high melting point that is difficult to be eroded by furnace slag as the raw materials, and added all kinds of nonoxides additive and carbon binding agent.
Oct 28, 2019· The refractory degree of high alumina brick can reach 1750℃~1790℃,It is a high quality refractory. Because of high aluminum refractory brick Al2O3, miscellaneous quality little, form the fusible vitreous less,so high refractoriness under load.
Nonmolded refractories are used to make refractory concrete and often include additives to ensure hardening at ordinary temperatures or after drying. Refractory concrete can be used to manufacture large blocks that weigh from 150–300 kg to 10–20 tons and even more; these are delivered in finished form to the construction site.
Refractory. One of a number of ceramic materials for use in hightemperature structures or equipment. The term high temperatures is somewhat indefinite but usually means above about 1830°F (1000°C), or temperatures at which, because of melting or oxidation, the common metals cannot be used.
Standard shapes are usually bricks that have a standard dimension of 9 × 4 1 ⁄ 2 × 2 1 ⁄ 2 inches (230 × 114 × 64 mm) and this dimension is called a "one brick equivalent". "Brick equivalents" are used in estimating how many refractory bricks it takes to make an installation into an industrial furnace.
Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal occurs naturally in this form and is the most stable form of carbon under standard high pressures and temperatures it converts to is used in pencils and lubricants.
Its high density does not usually provide adequate thermal insulation that instead is provided by a separate, porous, outer layer of refractory in brick, powder, or fiber form (the LTM refractory). This second layer is also the safety lining that provides backup in case of failure of the contact layer.
A fire brick, firebrick, or refractory brick is a block of refractory ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy .
offers 1,797 used fire brick products. About 84% of these are refractory, 6% are brick making machinery, and 3% are bricks. A wide variety of used fire brick options are available to you, such as mullite, alumina block, and alumina cement.
Standard shapes are usually bricks that have a standard dimension of 9 × 4 1 ⁄ 2 × 2 1 ⁄ 2 inches (230 × 114 × 64 mm) and this dimension is called a "one brick equivalent".

Refractory brick is refractory material with certain shape and size. Their shape has standard rules, but also can be built and cut as necessary temporarily according to the need. Refractory bricks for sale are made form refractory clay or other refractory raw materials with the color light yellow or brown.

It is well known that nonmetallic inclusions could form inside the steel or is descended from external sources like refractory bricks, slag or alloying materials. Theirs composition and size are directly depended of steel, slag or ceramic materials compositions. When the molten steel is treated in a ladle, the reaction between steel and

From today''s featured article Michael Collins (born October 31, 1930) is a former astronaut and test pilot who was the command module pilot of Apollo 11 in 1969. The first person to perform more than one spacewalk, he is one of 24 people to have flown to the Moon. Collins joined the Air Force after graduating from West Point in 1952. He graduated in 1960 from the Air Force Experimental ...
Refractory Refractory Nonclaybased refractories: Nonclay refractories such as those described below are produced almost exclusively as bricks and pressed shapes, though some magnesitechrome and alumina materials are fusecast into molds. The usual starting materials for these products are carbonates or oxides of metals such as magnesium, aluminum, and zirconium.
